WINDOW.

SPECIFICATION forming part of Letters Patent No. 392,924, dated November13, 1888.

Application filed December 2T, 1837. Serial No. 258,952. (No model.)

.To @ZZ whom it' may concern:

Be itxknown that we, HENRY S. KLEIN, of Milwaukee, in the county ofMilwaukee, and in the State of i/Visconsin, and HENRY E. KLEIN, ofChicago, in the county of Cook and State of Illinois, respectively, haveinvented certain new and useful Improvements in Windows; and we dohereby declare that the following is a full, clear, and exactdescription thereof.

Our invention relates to windows; and it consists iu certainpeculiarities of construction and combination of parts, to behereinafter described with reference to the accompanying drawings, andsubsequently claimed.

In the drawings, Figure 1 represents a front elevation of our invention,partly in section; Fig. 2, a partial vertical section of thewindow-frame; Fig. 3, an edge View of the sash; and Fig. 4, a horizontalsection on the line 4 4., Fig. 1. Figs. 5, 6, and 7 are detail views ofa latch that forms part of our invention.

Referring by letter to the drawings, A A represent the side pieces of awindow-frame that forms part of ourinvention, and each of these sidepieces is provided with a vertical channel, B, for a concaveguide-strip, C, the latter being preferably of metal and located betweenthe binding-strips D for the window-sash.

Each stile E of the window-sash has its outer edge out out-to form agroove, F, that gradually increases in depth from about the centertoward its extremities, at which points it is deepened laterally to formrecesses Gr G, as best illustrated in Fig. l. Secured to the stiles E Eof the sash, within the grooves F F, are semi-elliptic springs H, eachof the latter having its extremities bifurcated to form bearings for aroller, I, the one shown being convex upon its periphery to engage theconcave guidestrip C on the adjacent side strip, A, of the window-frame.

When the sash is placed in position, the springs H are contracted, andby their eXpansive force keep the rollers I snug against theguide-strips C, to compensate for loose play and thereby preventrattling. At the same time said sash can be more readily raised andlowered than is ordinarily the case, as owing to the action of therollers against the side strips there is no tendency to bind. When thesash is raised, the frictional contact of the rollers and guide-stripswill ordinarily hold said'sash in the position to which it has beenadjusted; but we prefer to provide one of the guidestrips C with aseries of .indentations or perforations, J, at suitable intervals apartto engage a rod, K, arranged to slide in the bottom rail, L, and thatstile of the sash that is adjacent to said indented or perforated guide-6o strip.

The rod K is pivotally connected to a springlever, M, by means of ascrew, N, said lever being in turn pivoted to a casing, O, that ismortised in the bottom rail, L, ot the sash. The spring-lever M ispreferably in one piece with a thumb-piece, I), that has its shankengaged by a segmental slot, Q, in the detachable faceplate R of thecasing O, said face-plate being also provided with a thumbpiece, S, bywhich 7o the sash may be raised.

To place the face-plate R of the casing O in position, it is so heldthat the free end of the thumb-piece P will pass through the segmentalslot Q, in said plate, and the latter is then given a quarter-turn tobring it into the position shown in Figs. l and 7. The under side of theface-plate is provided with a lug, T, that serves to preventdisplacement of the pivotscrew N. 8c

To raise or lower the sash the thumb-piece P is pressed downward todisengage the rod K from theindented or perforated guide-strip, and saidsash is then actuated by the grip of the operator on the thumb-piece S,belonging to the face-plate of casing O, both thumbpieces being graspedat the same time with one hand. The construction by which we accomplishthe operation just described is a decided advantage over the ordinarystyle of 9o window, wherein the lock has to be worked by one hand whilethe sash is raised or lowered by the other.

If found desirable, the opposing faces of the guidestrips C and rollersI may be dat, or in some instances we may omit said strips; and while wehave more particularly described our invention in connection with averticallyy operating sash, it may be as readily employed on the sashesthat work horizontally. roo

Our invention is very simple in its construe tion and can be readilyapplied to any window ata comparatively small cost.

Having thus described our invention, what We claim as new, and desire tosecure by Letters Patent, is-

l. In a window, the combination, with the frame and sash, of a slidingrod arranged in the sash to engage the frame, a spring-lever pivotallyconnected to the rod and provided withathumb-pieee, and a face-plate,also provided with a thumb-piece and having a Curved slot to engage thethumhpieee on said lever, substantially as set forth.

2. In a window, the combination, with the frame and sash, of a easingmortised in the sash, a spring-lever pivoted in the casing and providedwith a thumb-piece, a sliding rod pivotally connected to the lever andarranged in said sash to engage the i`rame,and a face-plate for theeasing, also provided with a thumbpiece and having a curved slot toengage the thumb-piece on the lever, substantially as set forth. Y

3. In a Window, the combination, with the frame and sash, ofguide-strips arranged on the frame and one of these guide-stripsprovided with indentations or perforations, semipiece on said lever,substantially as set forth.-

In testimony that We claim the foregoing We have hereunto sot our hands,at Milwaukee, in the county ol Milwaukee and State of Wisconsin, in thepresence of tWO Witnesses.'-
